9To load all objects in this library consult the events.loader utility
10file.
11
12The objects event_registry, before_event_registry, and after_event_registry
13implement convenient predicates for registering before and after events.
14
15The protocol event_handlersp declares the two basic event handler predicates
16(before/3 and after/3). You will need to refer this protocol in your objects
17if you need to use the super control structure (^^/1) with these predicates.
18
19The monitor object implements more sophisticated event handling predicates.
20
21Some of the objects assume that the used Prolog compiler defines the
22usual sort/2 built-in predicate.
